A novel technique for on-line location of Partial Discharges on medium voltage cables

In this paper, a simple and efficient procedure to model a medium voltage cable directly in time domain is presented. The proposed methodology, considering the skin effects and dielectric losses, takes into account the frequency-dependent parameters of the line. Based on the estimated propagation speed of the presented model, the laboratory and field testing results show that the accuracy Partial Discharge location of a medium voltage cable can be achieved.
